READ, a citithe invention is shown as applied to the win dzen of the United States,residing at New York, ing mechanism which operates upon the wi pcounty of Kings, and State of New York, have ing material used in plate-printing machines.

Fig. 2 assist by friction upon the reel in properly is a detail view of the reel-operating devices winding the material thereon. This roll M on alarger scale than that employed in Fig. 1. is operated by a pawl m', acting in conjunc- Ico 5o Fig. 3 is an end view of the devices shown in tion with a ratchet-Wheel m2, the pawl being Eig. 2. carried on one of the arms N' of a bell-crank which is journalcd on the shaft of the roll M. 'lhe other arm N of the bell-crank is connected to a rod O, which is given vertical movements by any suitable mechanism, the bell-.crankbeingtherebyoscillated. Thearm N of the bell-crank is connected by a suitable connecting-rod Q to the pawl-carrying arm 7;', so that the pull-olf roller K and the roll M are simultaneously rotated and an equal amount.

It is important in handling the wiping material which is used on the wipers of plateprinting machines to have the material drawn taut across the face of the wiper. In order to effect this, it is necessary to wind the material tightly on the wind-up reel. If the inaterial is not wound tightly on the wind-up reel, the slack is liable to be drawn backward from the reel, and thus to form folds or creases on the face of the wiper which interfere with its effective action. In order to insure that the winding material shallbe tightly wound upon the reel G and so stretched taut across the face of the wiper, the said reel G rests against a support, which is preferablyin the form of a roll M. Thematerial to be wound preferably passes around this roll or support and between it and the reel, and the frictional contact between the roll and the reel operates to tightly wind the material on the reel.

On the shaft II of the winding-reel is mounted a slotted lever R. This slotted lever engages an operating-pin n, carried on the arm N of the bell-crank before referred to, a snug connection, but at the same time one that permits the lever to slide on the pin, being secured by means of a screw n and washer '112, as is clearly shown in Fig. 3. The several parts are proportioned so that when the shaft H of the reel G is at the bottom of the slots I in the frame the operating-pin n on the arm N of the bell-crank will be substantially opposite the outer circumference of the reel G. 'lhe slotted lever R is formed with a hub or boss R5, through which passes the shaft II before referred to, the hub being secured on the shaft by means of a washer and screw. Extending upward from this hub or base is a short arm R', upon which is mounted a pin R2. On this pin R2 is hungaspringpawl R3, which engages a ratchet R4, which is mounted on the shaft II ot' the reel G. It is obvious that when the slotted lever R is operated by rocking the bell-crank the reel G will be rotated in the direction of the arrow in Figs. l and 2. Also mounted on the shaft H and between the ratchet-wheel R4 and the frame is a two-armed support, one arm of which, S, carries a spring-pawl S2, which acts to prevent backward movement of the ratchetwheel R4, and the other arm of which, S', extends up and is bent over to form a projection S3, which extends into the slotted bearing I and locks the support against rotation.

The parts being constructed and arranged as above described, it will be understood that when the bell-crank is operated through the rod O the rolls K and M will be simultaneously rotated and an equal amount. The roll K, operating in connection with the roll K', with which it frictionally engages, will act to pull oif a given amount of web of wiping material IV from the reel E, the web being led between these rolls. At the same time the reel G will be rotated by means of the slotted lever R, the pawl R3, and the ratchet-wheel R4, and it will turn the roll M and cause it to wind up an amount of wiping material equal to that which is pulled off from the reel E. As the wiping material accumulates upon the reel G the diameter of this reel will be increased by reason of the accumulation of web thereon, and since it rests directly upon the roll MV the reel will rise or be forced up in the bearings I, carrying with it the slotted lever R. As the slotted lever R is moved upward bythe reel G the pin in the bell-crank will engage it at successive points, each one of which is ata successivelyincreasing distance from the center of the shaft Il, upon which the slotted lever is mounted. The bell-crank therefore is acting upon a lever which is practically constantly increasing in length, but the pivotal point of which remains the same, and inasmuch as the throw of the bell-crank is constant the rotative movement imparted to the reel by the slotted lever R through the operating sources willconstantlydecrease. Since,furthermore, the pin N on the bell-crank lever is so located that it reciprocates in a curved line which is always practically tangent to the circumference of the reel G no matter what the diameter of this reel and the material woun d thereon may be the rotative movement imparted by it to the reel will vary and vary proportionately to the amount of increase in the diameter of the reel caused by the accumulation of material thereon.

It will be seen, therefore, that this device provides a reeling mechanism which is positive and sure in its action, is simple in construction, which will always act to cause the same amount of material to be taken up by the reel no matter what its diameter may be, and which will wind the material tightly upon the reel.

It is to be understood that the invention is not to be restricted to the precise means which have been herein described. Many modifications are possible, and it is to be understood that the invention includes all such modifications as are within its scope and spirit. I'Vhile, furthermore, the invention is primarily intended for use as a winding-up device,it is obvious that the mechanism might with slight changes be used as an unwinding or feeding-olf mechanism, and it is to be understood that such a use is contemplated.
